ABSTRACT:
A laminate type LC element includes a laminate defined by a plurality of stacked insulating layers. A first sheet-like conductor is formed between each pair of adjacent insulating layers to continuously wind and extend from between the pair of adjacent insulating layers to between another pair of adjacent insulating layers, the first conductor forming a coil having a preselected number of turns. A second sheet-like conductor is formed between each pair of adjacent insulating layers to continuously wind and extend from between the pair of adjacent insulating layers to between another adjacent pair of adjacent insulating layers, the second conductor being disposed in the face-to-face relationship relative to the first conductor through the insulating layers. The LC element has an increased capacitance and can reliably remove any external noise.
